Sorry, I misunderstood your original comment as referring to the the US.
However I don’t think that the system in China is like what happened with slavery (it is China you refer to?). People aren’t kidnapped, chained and transported in conditions that kill large numbers.
They aren’t traded in degrading markets and are not routinely beaten to death or mutilated by masters. They aren’t branded.
As bad as conditions currently are it doesn’t seem like slavery to me.
I wasn't talking specifically about China, or specifically about America colonialism style slavery. But I would bet that there are plenty of people kidnaped and forcefully transported around the country on China for labor, that's what that kind of government normally does.
They may not be traded on degrading markets, but that just make people valueless from the point of view of a dictatorship. And I do actually expect people are being mutilated by the Chinese government all the time, we just probably don't hear about it. Again, that what this kind of government normally does.
